Cruise lines prohibit passengers from bringing their own alcohol onboard as it's one of their big onboard moneymakers. An exception, however, does exist with wine as in most cases you are permitted to bring 1 bottle as long as it's sealed. As with all rules, there are always those looking to break them. Here's some insight into sneaking alcohol on a cruise.

<strong>Mouth wash bottle:</strong>  Fill up your Listerine or Scope with clear liquor and drop some green or blue food coloring into the bottle. Make sure you rinse the bottle very well or else your alcohol will taste like mouth wash. But then again, alcohol and mouth wash at the same time may not be such a bad idea!

<strong>Wine bottle:</strong>  Since in most cases you are permitted to bring 1 sealed bottle of wine onboard, take advantage of this. Purchase a wine bottle that you can open and re-seal, giving the illusion that it's never been opened. Empty out the wine and pour in your desired alcohol of choice. Voila!

<strong>Special purpose flasks:</strong>  There are companies who sell portable, flexible, plastic pouches designed specifically for sneaking alcohol on a cruise, to sporting events, or any other places that prohibit outside alcohol or liquids. These are growing in popularity because they cannot be detected by metal detectors. To find online, Google search terms such as "plastic alcohol pouch."

<strong>Keep it Private:</strong>  Don't let the crew see you pouring your smuggled alcohol into drinks;  Try to do so in private.  The crew is instructed by security to alert them if they observe anyone doing this.  Also you may get an angry response as they know that drinking your own booze results in smaller bar tabs and consequently smaller gratuities.

By sneaking alcohol on your cruise you'll definitely save lots of money.  So do your research and decide which approach works best for you.
